- Description
- Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
- The WBMP (Wireless Bitmap Image) file format is a monochrome graphics format optimized for mobile computing devices with limited display capabilities. It was developed for use in the early days of mobile internet to display images on mobile phones and other wireless devices with minimal processing power and storage. WBMP files contain bitmap images that are typically small and use a black and white color palette, making them highly efficient for fast loading times and minimal data usage.
